Arduino Technical Specs: 6. Analog I/O Pins(模拟输入/输出针脚) 8个 7. Digital I/O Pins(数字输入/输出引脚) 14个 Analog vs Digital: Analog(模拟) and digital(数字) signals(信号) are used to(被用于) transmit information(传输信息), usually through electric signals(通过电子信号). In both th...
/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...

Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5...
